Specification of Letters Patent.

Application firm August 6. 1907. Serial No. 387376.

Charging-Epxes, of which the following is a specification.

The object of my invention is to provide a new and improved furnace charging-box preferably made of cast-metal and as an-in- "tegral structure.

To this end my invention consists of a furnace charging-box, and in the novel features of construction, all as hereinafter described and claimed. v

In the accompanying drawing, which illus-' trates an application ofmy invention, Fig. 1

I is a part side elevational view and a part sectional view'of a charging-box embodying my invention and showing the head of a charging-arm in connection therewith; Fig. 2 amp plan; Fig. S'an end view; Fig. 4 an end view of the opposite end of the box particularly showing the charging-arm engagingmeans; and Fig. 5 a cross-section taken on in 5'5 of Fig. 2.

As shown the furnace. charging box .com prises a body 1, having sloping side-walls2 and straight end-walls 3 and 4. The upper edges of the side-walls 2 are each formed with a swelled or bellied-flange 5 extending. throughout the length of said walls. Each flange 5 is formed with its widest portion at [the middle of'the side-walls and is preferablg of the form as particularly shown by Fig.-

In addition to greatly strengthening the box the swelled or bellied flanges of the side-walls center the box during its passage into the furnace. The bellied flanges come into contact with the door-frame and cause the charging-box and charging-arm to swing into proper alinement with the door-frame or furnace charging-opening so that when the charge .is dumped and the box isbeing withdrawn the corners of the box will not strike thedoor-frame and will not injure said frame or the brick-work. As an operator cannot clearly see within the furnace in the act of-withdrawing a box and cannot determine when said box is in roper alinement with respectto the-furnace c arging-opening; 'the importance of providing means on the box for causing said box to assume the proper position for withdrawal is apparent. The upper edge of the rear end-wall 3 is also formed with a flange 5, similar to the flanges of the side-walls. 6 desi nate strengthemng ribs formed with the wafi 3.

Formed integral with the front-walla I.

employ charging-arm engaging-means designed to receive and engage a head 7 of the charging-arm 8; The engaging-means are in the form of a pocket 9 and comprise outwardly projecting and downwardly extending members 10. In additionto thee aging-means or pocket 9, the front-wa formed with .an opening 11 to receive the head 12 of plunger-rod 13.

14'. and 15 respectively designate the usual openings formed in the body and front and rear-walls.

What I claim is: I

1'. A furnace charging-box consisting of an integral cast-metal structure having s oping side-walls each formed with abellied-fiange, and meansformed integral with an end-wall of the box for engaging a charging-arm.

2. A furnace charging-box consisting-of an integral cast-metal structure comprisin side and end-walls each formed with a be liedfiange, means formed integral with one end-wall for e aging a charging-arm, and strengthening-i s formed integral with the "opposite end wall.

belliedfiang'e, means formed integral with one end-wall for engaging a chargm -arm, and strengthening-ribs formed integra with the opposite end-wall.

4. A cast-metal furnace charging-box consisting of an inte ral structure comprising sloping side-walls aving their upper edges flanged, said flanges being widest at the center of thebox and diminishingas they approach the ends, end walls, and means formed integral with an end-wall for engaging a charging-arm. i

In testimony whereof I affix my signature in presence of twowitnesses.
